No, but the "basic" chapter is trying to teach people what tables and
indexes are. I think it's reasonable to categorize FKs as a level
beyond that.
It would probably be fair to complain that window functions don't belong
in the same difficulty category as FKs. I stuck a chapter about them in
there because I didn't see any other good place for the material --- but
maybe we should consider breaking down the tutorial into
beginner/intermediate/"advanced" chapters?
